Objective

The mission of the Center for Real-Time Computing is to promote innovation in time critical applications like medical image analysis for Image Guided Therapy. The application of our focus is non-rigid image registration (NRR) for image-guided neurosurgery. The objective is to improve the performance, accuracy and usability of the existing method. There are two sub-projects we plan to explore.

1. Distributed parametric search for optimum parameter setting during NRR. This project includes three components: 1) development/evaluation of tools and methods for automated registration validation; 2) collection of ground truth data sets; 3) development of the high performance computing infrastructure.

2. Tetrahedral mesh generation for intra-cranial cavity discretization used in physics-based NRR.

Approach, Plan

1. Distributed parametric search:

  • need help with automated validation approaches, neurosurgery datasets
  • evaluate the infrastructure options: GWE/GSlicer3? web portal? TeraGrid?
  • are there other needs for this kind of large-scale computing?

2. Tetrahedral mesh generation:

  • meshing TCON Jun 19: no volume mesh generation discussed. What is (is there?) the need for tetrahedral mesh generation from NA-MIC projects?
  • status of unstructured grid visualization in Slicer3
  • meshing as a plugin in Slicer3
